I received notice that two of my previous questions were edited. Obviously, if those edits improved the question somehow, that's a good thing. So I went to check them out, also wanting to verify that the meaning of the question had not been altered.
When I loaded them and reviewed the revision history, I found that the only change was to alter the capitalization structure of the title of the question. I had capitalized as a title, and someone later decided they should be instead capitalized as full sentences.
Are these types of minor edits welcome? In my opinion, it seems minor enough to be considered arbitrary, which I think many users could find off-putting.
